Mitutoyo 510-131CAL Outside Micrometer 1 in Nist Cal

Product Description

The MITUTOYO 510-131CAL is a mechanical outside micrometer built for precision dimensional measurement in demanding shop and field environments. It covers a 1-inch measurement range with a graduation of 0.00005 inches and an accuracy of 0.00004 inches, making it suitable for applications where tight tolerances are non-negotiable. The friction thimble provides consistent measuring force between 5.0 and 10.0 N, reducing operator-to-operator variation. Measuring faces are solid carbide for long-term wear resistance. A NIST traceability certification is included, supporting quality-management and calibration documentation requirements. Licensed metrologists, tool-room machinists, and quality-control technicians are the primary users.

This micrometer is suited for precision measurement of external dimensions on machined parts, shafts, pins, and similar components in manufacturing, tool-and-die, HVAC equipment fabrication, and general mechanical trades. The rotating spindle design allows straightforward part engagement. The satin chrome finish reduces glare under shop lighting and resists surface corrosion during routine handling. The unit ships in a protective plastic case, making it practical for both bench use and field service kits where protecting calibrated instruments is a requirement.

Compatibility

Designed as a general-purpose outside micrometer for external dimensional measurement applications requiring NIST-traceable calibration documentation.

Installation Notes

Outside micrometers do not require mechanical installation but should be handled and stored in their protective case when not in use to preserve calibration. Before use, verify the zero setting against the reference standard supplied or per your facility calibration procedure. Avoid dropping or subjecting the instrument to impact, which can shift calibration. Recalibration by a qualified metrologist is recommended following any impact event or at intervals defined by your quality-management system.
